Very stange bus error on U2E

[BERTRAND Joël <joel.bertrand@systella.fr>]

	Hello,

	I use several sparc64 (and sparc32) for a very long time with 
debian/testing.

Boxes :
- U1E/170 MHz (Ui) with 640 MB, 73 GB raid1;
- U2E/2*300 MHz (Uii) with 2 GB, 73 GB raid1;
- U60/2*450 MHz (Uii) with 1 GB, 36 GB raid1;
- U60/2*450 MHz (Uii) with 1 GB, 73 GB raid1;
- U80/4*450 MHz (Uii) with 2 GB, 73 GB raid1;
- U420/4*450 MHz (Uii) with 4 GB, 300 GB raid1.

	All boxes use a up to date debian testing. On U2E, and only on this 
box, gcc (4.1 and 4.2) randomly hangs with bus error. In a first time, I 
have tested hardware with SUNvts (from solaris9). Hardware seems to be 
clean. This box is very stable (no other trouble), runs a 2.6.23.8 linux 
kernel. It's not a heat trouble (I use it for some computations without 
any trouble and I have verified its fans and cleaned it.).For example, 
it is very difficult to build gcc, but in stage3, when it use gcj to 
build java, I _never_ see any bus error.

	I don't understand why I see this bug only in my U2E. Any idea ?

	Regards,

	JKB
